Whitespace split issue, java

Question

beginner here I have searched anywhere but I can't seem to find any solution or problems related to mine. I've just started learning java and Here is my problem:

I have a working code where the input is split by "/":

Scanner d = new Scanner(System.in);
System.out.println("Enter your birthday (mm/dd/yyyy): ");
String birthday = d.next();

String[] bdayArr = birthday.split("/", 3);

int current = 2022;
int age = current - Integer.parseInt(bdayArr[2]);

now it was just a solution for the meantime as the date format I want to needs to be seperated with spaces (ex, January 21, 1899) and the purpose of me splitting is i need to get the year to use in a code block that computes the age of the person based on the birth year.

However, when i try to split it by whitespace I can't seem to access the array anymore. Error codes ranging from out of bounds to a NumberFormatException when i input (ex: January 21, 1989) (code below)

String[] bdayArr = birthday.split("\\s+", 3);

I don't know what i'm doing wrong, hopefully someone can help. (I know the question is too long and not straight to the point I wanted to provide as much context)

Answer 1

The problem is caused by d.next(), you should use d.nextLine() insted. to understand why you should check this quesiton What's the difference between next() and nextLine() methods from Scanner class?
